PRECISION STAMPING
Prototype and production stampings built for repeatability, fit, and long-run stability.
Anyone can make a sample part look good once. The real challenge is keeping critical features stable through thousands or millions of hits, then delivering parts that still run clean through plating, molding, assembly, and final use.
Gromax supports prototype and production stampings for parts where repeatability, fit, and long-run stability matter.
High-Volume Progressive Die Stamping
Built for repeatable, high-output production runs.
Consistent parts at scale, with stable quality and predictable piece prices runs.
DFM Support Before Tooling Starts
Design-for-manufacturability engineering up front.
Fewer tooling surprises, faster launches, and lower risk of expensive rework.
Tight Tolerances Where It Matters
Qualifying features down to ±0.0015” (part-dependent).
Better fit and function, fewer assembly issues, and higher yields.
Wide Range of Materials
Copper alloys, stainless steel, brass, nickel silver, CRS, beryllium copper.
Choose the best material for performance and cost—without adding suppliers.
Ultra-Thin & Foil-Capable Programs
Experience with delicate parts where edges and handling drive results.
Less damage and scrap on thin stock, with cleaner edges and more reliable outcomes.
Secondary Ops + Plating Coordination
Value-added operations managed end-to-end.
Shorter lead times and fewer handoffs—everything stays aligned to spec.
Packaging, Kitting & Line-Ready Delivery
Custom packaging and kitting to match your workflow.
Faster receiving and assembly, fewer errors, and smoother production flow.
Quality Deliverables & Compliance
SPC, PPAP, FAI/FAIR, inspection reports; ISO 9001:2015; ITAR-supported where applicable.
Easier audits, stronger traceability, and confidence for regulated programs.
frequently asked
questions
What tolerances can you hold on precision stamped parts?
We routinely support tight-tolerance stampings and review critical dimensions up front to match the process to the part’s function. Tolerance depends on material, thickness, feature size, and tool design.
Can you help improve the part for manufacturability?
Yes. We review geometry, tolerances, material, grain direction, burr direction, and feature spacing to reduce risk, improve consistency, and lower piece cost where possible.
What materials can you stamp?
We work with stainless steel, copper alloys, brass, beryllium copper, nickel silver, and cold-rolled steel, among others. We’ll recommend material based on strength, conductivity, corrosion resistance, formability, and cost.
What affects the cost of a precision stamped part?
The main drivers are material type and thickness, tolerances, part complexity, tooling, volume, plating, and secondary operations. We can also suggest changes that may reduce cost without affecting function.
What are your lead times for tooling, samples, and production?
Lead time depends on part complexity, material availability, tooling scope, and order volume. We provide clear timing based on the actual part and production requirements.
Can Gromax support repeat production and consistent quality?
Yes. We build repeatability into the tooling and process, with controlled inspection and production methods to support consistent quality lot to lot.
